Problems solved by technology

When a vehicle collides, the seat belt can often exert a large pulling force to restrict the movement of the occupant; but when the collision speed is very high and the intensity is particularly large, the force of the seat belt on the occupant may cause damage to the occupant's head and chest. harm

Embodiment Construction

[0023] figure 1 with figure 2 It is a structural schematic diagram of an energy-absorbing automobile safety belt according to an embodiment of the present invention. The fixed-point energy-absorbing car safety belt generally includes a split ring 2, the two open ends 21, 22 of the split ring 2 are respectively connected with the safety belt lock seat 4 and the seat fixing plate 1, and the two open ends 21, 22 can be opened under the action of external force and absorb energy through deformation. When a car collides, the split ring 2 deforms and absorbs energy, which can weaken the force on the seat belt waist, increase the movement of the waist, and make the waist restraint consistent with the head restraint, thereby increasing the energy absorption efficiency of the shoulder belt. Reduced damage to crew head and chest.

[0024] Further, an oblong closed ring 3 with a through groove 31 can also be provided for limiting the opening degree of the two open ends 21, 22 of the ...

Abstract

The invention provides a fixed-point energy-absorbing automobile safety belt, which includes a lock base and a split ring, and the two open ends of the split ring are respectively connected with the lock base and a vehicle body or a vehicle seat fixing plate, The two open ends can be opened under the action of external force and absorb energy through deformation. The energy-absorbing automobile safety belt of the present invention can elongate under a certain load during a collision because the split ring is arranged on the waist belt, which can improve the energy absorption efficiency of the safety belt, reduce the belt force of the occupant, and effectively protect the occupant's head and body. important parts of the chest.

Description

technical field [0001] The invention relates to a safety belt for automobiles, in particular to a fixed-point energy-absorbing safety belt for automobiles. Background technique [0002] The seat belt is the most basic occupant protection device. It can not only limit the forward movement of the occupant's body on the seat, but also limit the excessive forward leaning of the upper body. When the vehicle collides, it can prevent or reduce the occupant's injury. The modal safety belt that is equipped on the car at present is three-point safety belt, mainly comprises the shoulder strap that crosses the front chest obliquely and the waist belt that walks around the crotch of human body. The shoulder straps restrain the occupant's head and chest, and the lap belt restrains the occupant's lower body, such as thighs and buttocks. When a vehicle collides, the seat belt can often exert a large pulling force to restrict the movement of the occupant; but when the collision speed is ver...
